<div>
  This is a comma separated list (optional whitespace after commas) of email addresses
  that should receive emails.  May contain references to build parameters.
    To <em>CC</em> or <em>BCC</em> someone instead of putting them in the To list, add
    <tt>cc:</tt> or <tt>bcc:</tt> before the email address
    (e.g., <tt>cc:someone@example.com</tt>, <tt>bcc:bob@example.com</tt>).
